Title: Production of l-tryptophan by fermentation method
Inventor: UEDA YOSHIZUMI
IPC: C12R1/01
Filed: 1987-11-27
Abstract: PURPOSE:To enable production of L-tryptophan by a fermentation method by cultivating a microorganism, belonging to the genus Citrobacter and having tolerance to phenylalanine metabolitic antagonists and ability to produce the L-tryptophan. CONSTITUTION:Citrobacter.freundii OFPR36-11 strain, which is a variant strain, derived from Citrobacter.freundii FTR66-36 belonging to the genus Citrobacter and having tolerance to phenylalanine metabolitic antagonists, such as o- fluorophenylalanine, is cultivated in an ordinary liquid culture medium consisting of a carbon and nitrogen sources, etc., under aerobic conditions. The resultant culture solution free of microbial cells is then passed through a strong acidic cation exchange resin to adsorb L-tryptophan, which is then eluted with aqueous ammonia, etc. The obtained eluate is subsequently concentrated to provide crude L-tryptophan crystal powder, which is then subjected to decoloring treatment to afford the aimed purified L-tryptophan. This method is industrially advantageous, since the L-tryptophan can be accumulated in a remarkable amount without using an expensive precursor.

Abstract: PURPOSE:To prevent diffusion of substratum metal, by forming a substratum layer of 0.05-2.0mum in thickness in a specified region of a metal lead frame main body, by Ni-plating process using sulfamic acid Ni plating bath, and forming a noble metal layer on the substratum layer. CONSTITUTION:In a specified region of a metal lead frame main body having leads and pad parts, an Ni substratum layer of 0.05-2.0mum in thickness is formed by Ni-plating process using sulfamic acid Ni plating bath. In the case where the substratum layer is thinner than 0.05mum, the number of pin holes increases, and corrosion and diffusion of substratum metal can not be restrained. In the case where the thickness exceeds 2.0mum, cracks are generated in the substratum layer at the time of bending process. The thickness is desirable to be 0.2-1.0mum. After that, by Pd-plating process on the Ni substratum layer, a noble metal layer is formed of 0.2mum in thickness, and a lead frame is formed. Thereby excellent bondability and soldeability can be realized.
